dd 1508 in single cab

I'm gonna be doing a small systrm in one of my regular cab trucks and I don't have much room behind the seat. Maybe 1.5cu ft. and I am considering a dd 1508 or 1008. I am wanting a vented box and be capable of being audibly loud in the 30-48hz region. I am curious as to what people run them in box spec wise and if they are capable of playing 30hz pronounced and not sound like air.
